Add the following snippet to your HTML:. Read up about this project on. What Do I Build Next? It's been awhile since I last published any project. I make most of my purchases from Amazon, and back projects on Kickstarter, Indiegogo, and CrowdSupply. I was going to place this onto the Robot claw for "fine positioning". First I assembled, configured and tested the various StereoPi software packages, in hopes to incorporate Robot Stereo Vision.
I followed Wiki, posts and forum info from:. Here are pictures from the StereoPi build process: 1st unpacking. Here are pictures from the StereoPi build process: 2nd assembly and test. Assembly of the roller wheels Referring to a previously published project for software updates:. Christmas Morning,it's been awhile since I last visited this project.
I realized that I hadn't uploaded "Mobile Tank Video" demo. I need to revisit stereo streaming under robot control, that was lost after an "apt-get update" Note: I have extra, unused wires from motors that need cable management, battery and connectors as well.
I needed to extend video camera cables to incorporate pan-n-til servos as well: pan-n-tilt code will be incorporated in a later software update. As a starter for software and control of this project, I followed these useful links and guides:. These Available Guide s were consulted studied and expanded upon to build previous multi-track tanked vehicles:. Log in Sign up.

This means that we can connect it to the PC and make it appear as an USB stick, a serial interface, or — as exposed in this article — as an external network interface. It is very powerful but it comes with a few limitations due to the architecture of the Raspberry ecosystem followed by the StereoPi.

Here is our TL;DR step-by-step guide for creating this solution. The goal of this series of articles is to create a compact indoor robot that can navigate using stereo vision. Detailed TL;DR for fisheye cameras calibration can be found here in our blog.
The Art Of Stereoscopic Photo, part 1 basics. This code works with either the StereoPi or the Raspberry Pi Development Board, as both support using two cameras simultaneously. Our ready-to-use code and also Raspbian image will help you every step of the way, from the first image capture to the Depth Map created via real-time video capture. We would like to emphasize that all of these examples are for those new to OpenCV and are not intended for production use.

The software installation process is beyond the scope of this article but we have prepared a Raspbian image with all software installed. In this case, you will need to reboot StereoPi. After starting the script you can see a preview window with the stereoscopic video. This image will be used in the next scripts for Depth Map parameters tuning. This script allows you to check if your hardware is operational and helps you obtain your first stereoscopic picture.
In an ideal world, a perfect depth map needs to use two identical cameras with their optical, vertical and horizontal axis all in parallel. Thus, a software calibration method is used. Using two cameras you take multiple photos of an object.We are going to introduce here RuneAudioa free and open source software that we developed to replace the personal computer as digital source with a dedicated, cheap, silent and low-consumption board, running a custom-build Linux distribution.
It's a new-born project but it already offers many featuresit is under active development and it counts on a fresh but growing community. RuneAudio project has two main and clear goals. Our first goal is sound quality : we are working hard to get the best results from the Raspberry Pi and the other supported platforms, using Arch Linux as the base of our RuneOS and optimizing it as best we can for audio reproduction.
Our second main goal is to make it easy to use for everyoneso we developed a handly web interface RuneUI who lets users control the playback and system settings with absolute no need to use Linux command line. The web interface is cross-platform and responsive it adapts to screen sizemaking it accessible from every kind of device desktop computers, notebooks, tablets and smartphones.
The installation process is as easy as writing an. So let's begin with the short quick start guide. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Write the extracted. Make sure your SD card is not write protected before writing the image on it or before plugging it in your device.
When the write process has finished, safe unmount the SD card and plug it into your device. The Raspberry Pi is a very popular platform and has been used for every kind of projects. RuneAudio is a new-born project and we still are in a early development stage, so in the first beta releases some features are limited and there could still be some small bugs.Doom 64 ex mac
We invite you to give us your feedback in our forums and help us grow in number and quality. We hope you'll find our work useful for you, we put a lot of effort in it. Thank you for your attention! My problem is that the Pi won't boot. I use a 32 GB card, wrote the image with Etcher on the card and the only thing I get is a beautifull static rainbow screen.
Reply 2 months ago. Question 7 months ago.
So can this be loaded on a different distro instead of loading the bootable version mentioned? Also have been researching many reviews of hardware dac and amp options and find that opinions are like like belly buttons everyone has one, but not sure how reliable their opinions are since they seem to be biased in one direction or another.
Question 1 year ago on Step 3. I've tried a 1 terabyte drive and I keep having problems; the Pi takes forever to read all the files.Ever wanted to build a highly dangerous, inefficient, yet awesomely retro piece of electronics? Well, I have. That's pretty much what a tube amp is. Vacuum tubes are old electronic components that act like transistors, controlling a lot of current with a little current. You usually hear about tubes being used in guitar amplifiers, because they distort in a way that suits guitar playing.
However, tubes can also be used to amplify a stereo signal from another audio source such as a CD or MP3 player. Tube amps, unfortunately, aren't the most practical things in the world; they consume a great deal of power, get very hot, and are big. That being said, they look damn cool, and some people seem to think they sound pretty nice, too.
You can learn a lot about electricity and electronics from a project such as this. Going through the process of purchasing parts, planning, and executing is a useful experience for any maker.
Keep in mind that I am just a dude on the internet - take everything I say with a grain of salt. Except, of course, for these next few sentences. This project is dangerous in a very serious way.
It involves high voltages and a lot of current that can make you feel decidedly unpleasant or even decidedly dead. If you decide to work on it with the power on, be careful. Some of the capacitors in this amp will hold onto a charge for a long while after the power has been switched off. Discharge all capacitors through a resistor connected to ground, preferably with a voltmeter across it to be absolutely sure the cap has completely discharged.Building and booting StereoPi with the Raspbian OpenCV image
When testing the amp out for the first time, use something like a twelve volt power brick instead of plugging directly into the wall, just to be safe, as well as to prevent things from exploding or melting.
An old trick is to keep your left hand in your back pocket all the time, so if you do get shocked, it hopefully won't reach your heart.
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Parts The guy who originally designed this amp, Poindexter of Audiotropichas a wealth of information on his site about the parts he used.
His device, called the Musical Machine, is made up of some very nice, but very expensive audiophile-type components high quality specialty hookup wire, extra fancy solder. So, for that reason, I have built the same circuit as Poindexter, but with cheaper and more available parts. What You'll Need The amp consists of two sections, the audio circuit and the power supply.
Let's look at the parts in both. Enclosure You're going to need something to put your amp in, and there are definitely certain considerations to be taken when picking an enclosure. Transformers and especially the tubes themselves can get very hot, and so need to be in a well ventilated kind of area, preferably jutting out the top of the case.
Unfortunately, in my case, I foolishly chose an enclosure purely for its looks, which ended up being a bit of headache.
I picked an old wooden cutlery case, which just happened to have rather thick panels, making it painful to mount components that were designed to be mounted on circuit boards or thin metal project boxes.
So, unless you want to spend the time making that kind of case work, I'd say go with something more conventional.
